Image Playback Control for Mixed Still and Moving Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital still cameras struggle to display continuous captured images effectively, as they can only playback image files fragmentarily, making it difficult for users to grasp a continuous recorded image, especially when handling both still and moving image files.
Innovation Solution
An image processing apparatus and method that controls the display of both moving and still image data in a continuous mode, determining the type of data and adjusting display times, with options for variable-speed playback and graphical user interface overlays to manage playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual image files are played back separately, then each file can be displayed clearly, but the continuous captured image cannot be grasped
Solution Approach 1:
The patent merges multiple individual image files (both still images and moving images) into a continuous playback sequence. The playback control unit automatically transitions between files in chronological order, creating a unified continuous view that preserves both individual file clarity and overall continuous image context.
Solution Approach 2:
The patent implements continuous playback mode where the playback control unit maintains uninterrupted display across multiple image files. The system automatically progresses from one file to the next without manual intervention, ensuring continuous useful action of viewing the captured image sequence.
2Ease of manufacture
If multiple continuous moving image files are played back individually, then each file can be processed separately, but the playback stops frequently at file boundaries
Solution Approach 1:
The playback control unit eliminates interruptions by automatically transitioning between multiple moving image files in sequence. The system maintains continuous playback flow without stopping at file boundaries, significantly improving playback efficiency while keeping individual file processing simple.
Solution Approach 2:
The system performs preliminary organization of image files in chronological order and pre-configures the playback sequence. This preliminary arrangement allows the playback control unit to automatically progress through files without manual intervention, enhancing productivity while maintaining processing simplicity.
3Speed
If still image data is displayed for a short duration, then playback speed is fast, but the image cannot be viewed adequately
Solution Approach 1:
The playback control unit dynamically adjusts the display duration of still images based on the image type and playback context. Still images are displayed for an adequate predetermined time to allow proper viewing, while the system maintains overall fast playback speed by efficiently transitioning between files and utilizing faster playback for moving images.
Data Source
AI summary
An image processing apparatus controls display of a plurality of pieces of image data containing both moving image data and still image data, and includes: a moving image/still image determining unit that determines whether or not image data to be displayed is the moving image data or the still image data, when in a continuous display mode that displays the plurality of pieces of image data continuously in a predetermined sequence; and a display control unit that starts display control of the next image in response to finishing of display of all of the moving image data when the image data to be displayed is the moving image data, and starts display control of the next image data in response to finishing of display of the still image data for a predetermined time when the image data to be displayed is the still image data.
